Relational Operators in C++

Purpose: Relational operators in C++ compare values and return a boolean result (true or false).
Greater than (>) operator: Used to check if one number is greater than another.
Expression '7 >= 5': Evaluates to true because 7 is greater than or equal to 5.
Grade Determination: Without seeing the code snippet, it's impossible to determine the grade for a score of 90.
Main use: Relational operators are crucial for decision-making in programming, allowing programs to execute different code blocks based on comparisons.
Expression '5 < 6 && 9 > 3': Evaluates to true because both conditions (5 is less than 6 and 9 is greater than 3) are true.
Not Equal (!=) operator: Used to determine if two numbers are not equal.
Expression '8 > 10 || 6 < 3': Evaluates to false because both conditions are false (8 is not greater than 10, and 6 is not less than 3).
Expression 'x >= 5': Evaluates to true because the value of x is 5, which is equal to 5.
Expression '7 == 8': Evaluates to false, because 7 is not equal to 8.
Expression '7 < 5': Evaluates to false because 7 is not less than 5.
Expression 'x < 5': Evaluates to false because x is equal to 5, which is not less than 5.
Valid Relational Operators in C++: >=, <=, ==, !=, >, <
Expression '10 <= 10': Evaluates to true because 10 is less than or equal to 10.
